The Companion's location allows it to act as a gate between the educationally managed social media community and the external one. It permits mitigating the effect of external toxic content and offers the opportunity to recreate different interesting experiments about SM phenomena, such as the ones presented in [1]}, [2]}.
A controlled environment in which social network dynamics are emulated can be adopted to stimulate students to understand SM mechanisms better. Nowadays, the interactions intervening in social media are often mediated by automatic algorithms. Most teenagers ignore these dynamics that heavily influence their content and behavior when virtually interacting [3]}.
For example, in a classroom, it may expose sub-groups to recommendations with different biases or allow the students to change the recommender parameters [4]}.
